Ok. So I'm usingy Apollo vtube (V1), with a phiniac tank and a 3.0ohm boge carto. I slotted my carto nice and wide with my dremel. First fill of the tank with JC Tundra 1.1%, it worked and tasted beautifully. The best flavor I've tasted in awhile. The next day, I vape it the same, and the draw is tighter and the flavor tastes burnt. Shortly after then, I knew it killed my carto. I tried again with 50/50 cutter and a new carto, and same thing happened again. Is there any possible way to vape JC's redoak line tundra without frying a carto? Any similar experiences here or am I alone on this one? Just wondering.
